I can vouch for this one..... it even makes sense for extra-low-cost dual node configurations with a degraded server (DEGRADED=== really small PC that will provide bitch slow service, but thats better than none at all) for example, for single webmail servers. Its a whiff to configure with heartbeat and all....pretty cool stuff I use it in a somehow similar (to what i described above) setup with about 10/15 thousend mailboxes and vhosted homepages. > You can find some descriptions as well as a download link at the > following URL: > > http://www.complang.tuwien.ac.at/reisner/drbd/ > > If you decide to give it a try, I'd be very interested to hear from > your experiences. > > Regards, > > Oliver -- Alex Borges (lex) <[EMAIL PROTECTED]> Step One Group -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
